Plus, power now won't be as affected by weather conditions (rain/snow) as it was before. It's also resulted in a huge change to how much finger force is require to achieve a certain amount of deceleration - I just lightly squeeze the brake and my speed just disappears. I never realized before that braking required hand strength, but now I'm now really enjoying the fact that it requires almost no effort.

BTW, if you want to add some interruptor / bar-top brake levers then the Tektro RL740s are the only ones designed for V-brakes / mountain discs, I'm using one and it has a great feel to it. Once I've got a more appropriate front rim, I'm planning to post pictures on the cyclocross forum.
